Also what her japanese fans want is usally different to what her world fans want, and those are the ones who she mainly caters for, since its where she is from and where she preforms
like with her 15th anniversary vote poll thing, basically all her asian fans want the songs her western fans are sick off
but we have to think this tour is about her 20 years, so her old classics will be brought into it, we cant be too surprised there.
Also music isnt as big a money maker know with pirating and itunes, think instead of getting a cut of +$30 per single and up for her other stuff, to getting a cut of $1.99 per single. Not saying shes poor or running out of money, just that the return isn't as big for what is spent
